The aim of this study was to identify useful prognostic factors in patients undergoing pancreatoduodenectomy for distal cholangiocarcinoma. The records of 36 patients with distal cholangiocarcinoma undergoing pancreatoduodenectomy were retrospectively reviewed. Potential clinicopathological prognostic factors that may affect survival were examined by univariate and multivariate analysis. There was no mortality. Overall survival rates were 75%, 54%, and 50% for 1, 3 and 5 years, respectively (median survival time, 26 months). Univariate analysis found that age (≧ 65 years), pancreatic invasion, duodenal invasion, lymph node metastasis, perineural invasion and a positive surgical margin were significant predictors of poor prognosis ( P < 0.05). Furthermore, lymph node metastasis was found to be a significant independent predictor of poor prognosis by multivariate analysis ( P = 0.043). Moreover, there were significant differences in the 5-year survival between patients with 2 or less involved lymph nodes and those with 3 or more positive nodes ( P < 0.001). There were no 2-year survivors of the group of patients with 3 or more positive nodes. These results suggest that the presence and number of lymph nodes exhibiting metastatic disease might be useful in predicting the postsurgical outcome in patients undergoing pancreatoduodenectomy for distal cholangiocarcinoma.
